FIRE-G RATE.

SPECIFICATION forming part of Letters Patent No. 247,337, dated September 20, 1881.

Application filed March 23, 1881. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT GILonRIEsr, a citizen of the United States, resident at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Fire-Grates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a representation of a vertical section, and Fig. 2 is a front view.

This invention relates to improvements in grates.

In the annexed drawings, A represents a fire-place, having sides a a, back a, and concave top B.

To the sides a a, at the front, are secured the studs 0 o, and below these, to the back, the studs D D.

E is the grate.

F is the front, having at its ends the depending lugsff, and at the top the inwardly and downwardly projecting hooksf f and outwardly and downwardly projecting hooksf f G is the bottom, consisting of bars g and cross-bars g 9 The front and grate are seated -in the fire-place by hooking the hooks f f over studs 0 c and letting the rear cross-bar, 9 rest on studs D D. The ends of rear crossbar, g front cross-bar, g, and the outside bars, 9, form the projections m n p, which come in contact with the inside of the fireplace, and by which the grate-body is held oft. This allows a free circulation of air all around the fuel, materially increasing the combustion. The arrangement described gives a slope to the grate bottom, exposing more surface to the draft and assisting greatly in get-ting out the ashes, thereby permitting the heat to pass out more freely.

By hooking the outwardIy-projectiug hooks f f which are lower than hooksff, upon the studs 0 0, greater pitch and less capacity will be given the grate, and the bottom surface will be better exposed.

The concave B at the back and above the fire operates to collect and throw the heat-rays convergently to the front, and out into the room, giving greater warmth from'the same amount of fuel.

What I claim is- 1. The grate E, provided with projections f f constructed as described, whereby the position oft'he grate can be changed.

2. Front F, having lugs fand hooksff in combination with bottom G and a tire-place, having studs 0 c at the front and D D at the rear, as set forth.

3. The grate, having the inwardly and outwardly downward projecting. hooks.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT GILGHRIEST.
